We installed a PowerServer 2020 in a server and deployed a mobile application there that connects to an Oracle database. It all worked correctly and our customer could begin to work with it.
But some days later the mobile application began to to throw an error when connecting to the database:
System.Data.OracleClient requiere la version 8.1.7 o posterior del software cliente de Oracle
This server has an Oracle 12 client that connects to the datase correctly. We test the connection with a PowerBuilder 2019R3 that is also installed in this computer and it also works. But if we test the connection in the PowerServer AEM it fails with the same error. It seems that PowerBuilder and PowerServer connect to the Oracle database in different ways, but I don't know what they are.
We have tried to follow some instructions like this one:
But it does not solve our problem. Any ideas?
Thank you for you help.
